While there is some weak and inconclusive indication for blood type preference from older publications, the research persistently shows CO2 plume, body odor produced by certain bacteria and heat (mostly in that order to guide the mozzie from several meters away to the exact blood vessel) as most important cues that lead to host identification, attraction and feeding, through all tested anthropophilic/mammalophilic genera within the family Culicidae. https://pmc.ncbi.nlm.nih.gov/articles/PMC10789295/
Well, 8 if you include + or - types. And there are many more than that, but for most purposes the 8 are differentiated enough
I dunno, I can sit by my husband and not get bitten, they don’t like me much so unless there is no other choice they leave me alone. I think they like people who are warmer and emit more carbon. It doesn’t seem like blood type is a strong factor.
I typically run pretty hot, and am typically not mosquitos favorite target. Though if mu oura ring is to be believed, I have a low resting heart rate, which may indicate lower carbon emmissions. So maybe thats it
Studies have consistently shown for the past couple decades that mosquitos are attracted to O blood. There are other factors, too. They like people who eat a lot of bananas, so maybe they like potassium? Carbon dioxide is also a target.
If only were that simple. My wife and I are both type A pos. If we’re both outside, they will swarm her, and leave me alone. If I’m outside alone, they can be bothersome enough to go back inside.
Not type O and mosquitos chow on me
Am type O and mosquitoes always leave me alone if there’s others around.
In lab experiments, mosquitoes seem to prefer feeding on people with type O blood, although other genetic factors also play a part.
That makes sense since it’s basically fake research that doesn’t prove anything about the matter
They bite me like 10 times around my knees and 2 times on my fingers the other day (wednesday last week). I was carrying long pants. I still don’t know how they did that. It still itches.
I’m type O. My mother, who was next to me, is type A. She wasn’t bitten even once.
Me and my kids must be O, then. It’s been a pain all my life, being so delicious, living where I live.
